Even for 30 seconds. Even when you put the big rocking horse in front of the drawers / cabinet and put up all off-limits things. In our house, momentary silence means trouble. And big messes.
(Believe it or not, this is not a very big deal. It is when the bookshelves are emptied of books and all of the puzzles are dumped out that I want to cry inside.)
Enjoy your moments of silence!
(Heaven knows I don't!)
